Repeats as global DNA methylation marker in bovine preimplantation embryos [PDF]
DNA methylation undergoes dynamic changes and is a crucial part of the epigenetic regulation during mammalian early development. To determine the DNA methylation levels in bovine embryos, we applied a bisulfite sequencing based method aimed at repetitive

The use of retrotransposon-based molecular markers to analyze genetic diversity [PDF]
Molecular markers play an essential role in all aspects of genetics, modern plant breeding, in human forensics, for map-based cloning of genes, ranging from the identification of genes responsible for the desired traits to the management of backcrossing ...

Retrotransposons and Telomeres
Abstract Transposable elements (TEs) comprise a significant part of eukaryotic genomes being a major source of genome instability and mutagenesis. Cellular defense systems suppress the TE expansion at all stages of their life cycle. Piwi proteins and Piwi-interacting RNAs (piRNAs) are key elements of the anti-transposon

Defending the genome from the enemy within:mechanisms of retrotransposon suppression in the mouse germline [PDF]
The viability of any species requires that the genome is kept stable as it is transmitted from generation to generation by the germ cells. One of the challenges to transgenerational genome stability is the potential mutagenic activity of transposable ...

June 27, 1970 was a significant day for our understanding of both the flow of information in biological systems and the evolution of eukaryotic genomes as this was the day that Nature published back-to-back papers reporting the discovery of an enzyme that copies RNA into DNA. This soon became known as reverse transcriptase and the RNA tumour viruses in

Occurrence of LINE, gypsy-like, and copia-like retrotransposons in the clonally propagated sweet potato (Ipomoea batatas L.) [PDF]
Retrotransposons are a class of transposable elements that represent a major fraction of the repetitive DNA of most eukaryotes. Their abundance stems from their expansive replication strategies.

Isolation of a transcriptionally active element of high copy number retrotransposons in sweetpotato genome [PDF]
Many plant retrotransposons have been characterized, but only three families (Tnt1, Tto1 and Tos17) have been demonstrated to be transpositionally competent.

Retrotransposon silencing by DNA methylation can drive mammalian genomic imprinting [PDF]
Among mammals, only eutherians and marsupials are viviparous and have genomic imprinting that leads to parent-of-origin-specific differential gene expression. We used comparative analysis to investigate the origin of genomic imprinting in mammals. PEG10 (

Communication between distant cells can be mediated by extracellular vesicles (EVs) that deliver proteins and RNAs to recipient cells. Little is known about how EVs are targeted to specific cell types.

Retrotransposons are major components of higher plant genomes, and long terminal repeat (LTR) retrotransposons are especially predominant. Thus, numerous LTR retrotransposon families with high copy numbers exist in most plant genomes.
